I could probably be described as a SpaceX enthusiast. I catch their launches when I can, and I’ve watched the development of Starship with great interest. But the side-effect of SpaceX’s reusable launch system is that getting to space has become a lot cheaper. Having excess launch capacity means that space projects that were previously infeasible become suddenly at least plausible. One of those is Starlink.

Starlink is SpaceX’s satellite Internet service. Wireless and cellular internet have helped in some places, but if you really live out in the sticks, satellite internet is your only option. And while satellite Internet isn’t exactly new, Starlink is a bit different. Hughesnet, another provider, has a handful of satellites in geostationary orbit, which is about 22000 miles above the earth. To quote Grace Hopper, holding a nearly foot-long length of wire representing a nanosecond, “Between here and the satellite, there are a very large number nanoseconds.”

SpaceX opted to do something a bit different. In what seemed like an insane pipe dream at the time, they planned to launch a satellite constellation of 12000 birds, some of them flying as low as 214 mile altitude. The downside of flying so low is that they won’t stay in orbit as long, but SpaceX is launching them significantly faster than they’re coming down. So far, nearly 1600 Starlink satellites are in orbit, in a criss-crossing pattern at 342 miles (550 km) up.
